We have been having some fun lately at the expence of a persistent Troll on this forum so I thought I'd do some research to better understand his strategy. The link above is about what Trump does ... but obviously the style is similar. Hope you like the read.
I've read a few articles and this .. and while no one strategy is foolproof this is what I've come up with so far ...
Key elements to address this type of troll appear to be to have fun with him and to point out the lies.
Pointing out positive news is golden ... and to really push reality ... he will push back with an unreal version (his reality) btw.
No need to be mean since an important part of his strategy is pushing a negative tone ... better to have fun with him and laugh :)
